ALGORITMA OPERASI TEKUK KOLOM
1. Algoritma Program Tekuk Kolom
a. Algoritma cara hitung langsung
1. Memulai
Menjalankan program
2. Memilih perletakan
Membaca data pilihan yang telah dimasukkan:
2.1 sendi - sendi
2.2 sendi – jepit
2.3 jepit – jepit
2.4 jepit - bebas
3. Memilih penampang
3.1 penampang T
3.2 penampang L
4. Memilih jenis bahan penampang
4.1 bahan baja = 120000 mpa
4.2 bahan alumunium = 200000 mpa
4.3 bahan beton = 20000 mpa
4.4 bahan lainnya (memasukan data sendiri)

5. Memilih panjang batang
L
6. Memasukan nilai dimensi a,b,c,d (milimeter)
a b
c a
b
d c d
7. Tampilkan hasil perhitungan
7.1 Ix kanan-kiri
7.2 Iy atas – bawah
7.3 Pmax
7.4 P diperbolehkan
8. Selesai
